[0024] Preferably, the spherical inner cavity 5 and the square inner cavity 6 are connected to each other, and the spherical inner cavity 5 is located on the top of the square inner cavity 6 .

[0025] When in use, the hot air blower 12 blows out hot air from the bottom of the drying box body 1. The hot air rises from bottom to top, and when it flows through the spherical inner cavity 5, it flows back along the spherical inner wall of the spherical inner cavity 5 to form a circulation, thereby efficiently drying the surface of the placed paper and plastic.

[0026] Preferably: the uniformly heated component includes: a motor 7, a connecting column 8, a coupling 9, a placement plate 10 and a through hole 11, the motor 7 is installed on the top of the drying box body 1, the output end of the motor 7 passes through the top of the drying box body 1 and is connected to the connecting column 8 through the coupling 9, the through holes 11 are evenly spaced on the surface of the placement plate 10, the placement plates 10 are symmetrically arranged and fixedly connected to the surface of the connecting column 8, and the placement plates 10 are evenly spaced and staggered along the vertical direction of the connecting column 8, the motor 7 and the hot air blower 12 are electrically connected to the external power supply through the control panel 4, and it should be particularly noted here that: the rotation speed of the motor 7 should be controlled within 5-10r / min.

[0027] During specific use, the operation of the motor 7 can cause the connecting column 8 to rotate, thereby driving the paper plastic placed on the placement plate 10 to rotate, so that the surface of the paper plastic is fully in contact with the heat flow in the drying box body 1. Secondly, the heat flow from the bottom to the top of the drying box body 1 will also flow through the through hole 11 and effectively contact the bottom surface of the paper plastic. The staggered arrangement of the placement plates 10 can also facilitate the upward circulation of the heat flow, thereby further improving the drying effect and drying efficiency of the paper plastic, and achieving efficient drying of the paper plastic.
